The release date of one of HP’s upcoming webOS tablets, codenamed Opal, popped up on Engadget this afternoon courtesy of an anonymous tipster, along with renders of a second model codenamed Topaz. Some of the Topaz’s specs, like a front-facing camera and buttonless bezel, could be seen from the renders, while a release chart for Opal indicates most models will be out by September of this year.

Rendered front and back shots of the 9-inch screen Topaz tablet show it will have a microUSB outlet, front-facing camera, and no buttons on the bezel or sides. Engadget speculates that the HP tablets will have a three-speaker arrangement, with two on the left side and one on the right, for stereo sound in both landscape and portrait mode.
